Mrs. Minton has a problem with her kitchen sink, so she calls a plumber to fix it. The plumber charges $14.95 to come to the house and $27.50 per hour for the repair. The plumber sends Mrs. Minton a bill for $138.70. Write an equation that you could solve to find out how many hours it took the plumber to fix Mrs. Minton's sink. Be sure to define your variable.​

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
